VALVE FOR VENTILATED SHOES.

SPECIFICATION formingpart of Letters Patent No. 635,101, dated October17, 1899.

Application filed December 16, 1898. $erial No- 699,505. (No model.)

To all whom it may concern:

Be it known that 1, JOHN ERNEST KENNEDY, of the city and district ofMontreal, in the Province of Quebec, Canada, have invented certain newand useful Improvements in Valves for Ventilated Shoes, of which thefollowing is a specification.

My invention relates to improvements in valves for ventilated shoes; andthe object of the invention is to devise a valve, automatic in itsaction and simple in its construction, which will effectually providefor a thorough ventilation of the foot in the boot or shoe; and itconsists, essentially, of two casings, one fitting within the other, theinner one being provided at its inclined inner end with a hinged flapand the outer one having an L- shaped slot into which extends a pin fromthe inner casing, whereby the movement of the casing and the hinged flapmay be limited and looked, as hereinafter more particularly explained.

Figure 1 is a sectional view showing my improved valve permanentlyclosed. Fig. 2 is a longitudinal. section through the casings, showingthe inner casing adjusted and the hinged flap raised in position to openand close. Fig. 3 is a sectional perspective view of the outer casing.Fig. 4 is sectional perspective detail of the inner casing and flap.Fig. 5 is an exaggerated perspective detail of the inner casing and flapseparated.

In the drawings like letters of reference indicate corresponding partsin each figure.

My invention is intended to be used in connection with a collapsibleinner sole which operates to draw in air through a suitable orifice inthe boot when the foot is raised in walking and the sole therebypermitted to expand and to force the air to rise around the foot whenthe foot is placed on the ground, which compresses the sole.

A is the heel of the boot; B, the sole; 0, the collapsible inner sole,and D the insole. The heel A is usually comprised of several lifts a.Before the undermost lift or lifts are put on a hole a. is bored throughthe upper lifts and then the last lift is put on and a hole a? is boredlaterally from the front of the heel, so as to connect with the hole a.The

hole a of course extends through the sole B to an open space in thecollapsible inner sole.

Although I describe this manner of making the holes for the insertion ofthe valve and also describe the heel as being comprised of severallifts, it will be readily understood that the holes may be bored in anysuitable way, and the heel, instead of being in lifts, may be in onepiece.

E-is the outer casing, which is open at each end and is provided withspicular projections e at the inner end having an incline outwardly,-sothat when the casing E is inserted into the hole 0L2 such spicularprojections will hold such casing in position. The casing E is providedwith aslot e, which has a notch e boost the inner end, making the slotL- shaped.

E is a sleeve fitting within the casing E and provided withan inclinedinner end.

F is the inner casing, provided with a stopflange f, preferably with amilled edge at its outer end andat the side with a limiting-pin j, whichextends into the slot 6 in the easing E, and when the inner casing F ispulled out and slightly turned the limiting-pin f is in the notch 6thereby securely lockin g the casing F in its open position. The casingF has an inclined inner end, the incline of which corresponds to theincline of the inner end of the sleeve E. The inner end of the casing Fis also provided with hollow journalteats f, between which fits thehinge-boss f? of the flap F. Through the journal-bosses f and hinge-bossf extends the hinge-pin f. In order to bring the stop-flange fnearlyflush with the heel, I turn up a flange e on the outer casing E-and sink it sufliciently into the heel, leaving space enough around theflange fto insert the thumb-nail or a suit able instrument to pull outthe casing F.

The flap F is preferably provided with a weight-bulb f the sleeve Eserves as a means of limiting the throw of thevalve-flap F. v

Under ordinary circumstances when the valve is open, as shown in Fig. 2,and a person in walking places his foot upon the ground he wouldnecessarily collapse the inner sole both on the sole and heel of theboot, thereby serving to close the weighted valve-flap F and cause theair to pass up through the perforations in the insole around the foot.Upon raising the foot the inner sole will expand,

The inclined inner end of and the suction thereby caused Will draw thevalve-flap inwardly, thereby opening the same, and the air will passupwardly through the hole a into the spaces of the collapsible innersole. Upon placing the foot down again this fresh air is caused toascend through the openings cl around the foot. This operation isrepeated continuously as long as the casing F is pulled into its outwardposition, and the foot is thereby kept thoroughly ventilated andconsequently dry and comfortable and free from moisture or perspiration.

Should the wearer of the shoe be Walking in a Wet place, he can merelypush in the easing F, and thereby completely close against the ingressof water or air into the shoe.

What I claim as my invention is 1. A Valve comprising an outer casing,an inner casing slidable longitudinally therein, a flap carried therebyand a fixed stop in said outer casing adapted to prevent the movement ofthe flap, substantially as described.

2. A Valve comprising an outer casing, an inner casing slidablelongitudinally within the same, a flap pivoted to the inner end thereofand a sleeve fixed in said outer casing adapted to lock the fiapagainstmovement, substantially as described.

3. A valve comprising an outer casing, an inner casing slidable therein,bearings extending from the upper part of the inner periphery of saidinner casing, a flap pivoted in said bearings and a sleeve fixed in theouter casing, substantially as described.

4. The combination with the outer casing having an L-shaped slot, of theinner casing having a flange at the outer end andan inclined inner endprovided with a hinged flap and a pin extending from the inner easinginto the slot in the outer casing as and for the purpose specified.

Signed at Montreal, Canada, this 12th day of December, 1898.
